Alex Gibney’s work-in-progress Untitled James Brown Documentary and the world premiere of Björk: Biophilia Live will screen.

Tribeca Film Festival have added two music documentaries to the line-up, which kicks off with the previously announced world premiere of Nas documentary Time Is Illmatic on April 16.

“Music is a prominent thread throughout the festival this year, and the Untitled James Brown Documentary and Björk: Biophilia Live are great complements to our already exciting slate,” said director of programming Genna Terranova.

“Nas and his work have been beloved by New Yorkers for years and we are thrilled to be celebrating his music with everyone on opening night.”

Gibney’s Untitled James Brown Documentary (US) profiles the iconic soul singer and is made in cooperation with the Brown estate. Gibney will take part in an on-stage conversation after the screening on April 27.

Nick Fenton and Peter Strickland directed Björk: Biophilia Live (US), which chronicles the Icelandic performer in concert and incorporates animation. It will screen on April 26.
